Ingredient review
Coco-Morpholine Oxide
INCI: COCO-MORPHOLINE OXIDE
A gentle, coconut-derived surfactant that helps create rich foam without stripping the skin.
In plain English
Coco-morpholine oxide is a mild cleansing ingredient made from coconut oil. It helps shampoos and body washes produce a thick, creamy lather while being less harsh than traditional sulfates. Because it's gentle, it's often used in products for sensitive skin or in formulas that aim to clean without drying out the skin.

Quick decision guide
Useful, but context matters
Coco-Morpholine Oxide is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Coco-Morpholine Oxide.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant derived from coconut fatty acids and morpholine, an amine compound. It belongs to the amine oxide family, known for their mildness and foam-enhancing properties.
How it works
It reduces the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. It also stabilizes foam, making the lather feel richer and more luxurious. Unlike stronger surfactants, it does not strip the skin's natural moisture barrier.
Pros
Gentle cleanser
Coco-morpholine oxide is much milder than sodium lauryl sulfate, making it suitable for daily use without over-drying the skin.
Foam booster
It enhances the foam quality of cleansers, giving a satisfying lather that many users prefer, even in sulfate-free formulas.
Cons and cautions
Synthetic origin
Although derived from coconut, it undergoes chemical processing, which may not align with all-natural or minimal-ingredient preferences.
Potential irritation at high levels
At concentrations above 5%, it can cause mild irritation for some individuals, though this is uncommon in commercial products.
Best for
- People with normal to dry skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals with known sensitivity to amine oxides (rare)
Usage tips
Safety summary
Coco-morpholine oxide is considered safe for use in cosmetics at typical concentrations. It has low irritation and sensitization potential, though very high concentrations may cause mild irritation. No significant health risks have been identified in regulatory reviews.
Research notes
The Cosmetic Ingredient Review (CIR) panel reviewed amine oxides, including coco-morpholine oxide, and concluded they are safe for use in rinse-off products. Studies show low acute toxicity and minimal skin irritation. Research is ongoing but supports its safety profile.
Common label clues
- Typical concentration
- 1–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off products.
- Common uses
- Shampoos, Body washes, Facial cleansers, Shaving creams
- Environmental note
- Coco-morpholine oxide is biodegradable, but its production involves synthetic chemistry. It is not typically associated with significant environmental concerns.
Good to know
- Coco-morpholine oxide is often used in 'sulfate-free' shampoos to improve lather without harshness.
- It is biodegradable and generally considered safe for aquatic environments.
